Product name: Sn99Cu0,7Ag0,3 1.1.3
Alloy designation in accordance with ISO 9453:2014:
Sn99Cu0,7Ag0,3 (501)
Product type: Cored solder wire
Flux: 1.1.3

1. General characteristics

The solder was produced in the first smelt of tin, silver and copper. The composition of the solder complies with the ISO 9453:2014 standard. 1.1.3 solid flux is based on rosin and halide free formulations. Low silver lead-free alloy is intended for professional mechanized soldering in electronics where meeting the requirements of the RoHS2 Directive is required.
